Channel is basically a white label instance of PatchWork, which is a Mastodon fork with custom feeds and community curation tools.
The main intent behind the project is to help existing communities and organizations get onto the Fediverse, and have some curation capabilities. Ideally, it can be used to get a large amount of people and accounts onto the network with minimal friction.
Wanting to get paid for your work, so that you can keep making stuff, is in fact not the same thing as greed. We have this assumption that everything on the Web should be free, or at least helped along by donations, but it’s not sustainable.
